Floating Ping Pong Ball – Sick Science! #137
Get the secret here: http://www.stevespanglerscience.com/experiment/floating-ping-pong-ball
You’ve seen Steve Spangler use blow dryers or industrial-sized blowers to levitate ping pong balls, beach balls, and send toilet paper flying through the air. You can replicate this levitating object phenomenon on a smaller scale using objects that are right in your home! The Floating Ping Pong Ball trick uses amazing principles of air that are sure to amaze anyone, from your science teacher to your parents to your neighbors!

Because its hollow
First, the air you blow is what goes to the funnel and that air is being dispersed or simply, spread to the outer parts.
IT DOESNT BLOW AWAY BECAUSE OF BERNOULLIS PRINCIPLE
The Floating Ping Pong Ball is a wonderful example of Bernoulli's Principle, the same principle that allows heavier-than-air objects, like airplanes, to fly.
Bernoulli, an 18th century Swiss mathematician, discovered something quite unusual about moving air. He found that the faster air flows over the surface of something, the less the air pushes on that surface. That means that the air pressure on the object is lower than average.
The air from the straw, as you blow through it, produces the levitating ball phenomenon using Bernoulli's Principle. The fast air moving around the sides of the ball is at a lower pressure than the surrounding, stationary air. If you look closely, you'll see that the ball wobbles while it is levitating in midair. The ball is attempting to leave the area of low pressure, but the higher air pressure surrounding it forces it back into the low pressure area.
Sorry but get better less annoying music
I have tried this but it does not work for me. ?Leaf blower works better 🙂
The ball is caught inside the air blow due to the shape of the cut-bottle.
The bernoullie effect
you blew it?
Cause when you the air hits the egg it goes up cause of the air going that direction
because when you blow it the air your blowing surrounds the ball so it wont fall
